Grizzly H8101 - Horizontal Stirling Engine Kit

Please note that this item is discontinued and no longer available for sale.

The Stirling Engine was invented in 1816 and operates on hot air that alternately expands and contracts to drive two pistons connected to a flywheel. The air is heated by an alcohol burner and the greater the temperature differential, the faster the speed. This kit includes the castings and raw parts required, so you can machine everything yourself—a great project for the aspiring machinist! For those who don't want to machine their ow...

The Stirling Engine was invented in 1816 and operates on hot air that alternately expands and contracts to drive two pistons connected to a flywheel. The air is heated by an alcohol burner and the greater the temperature differential, the faster the speed. This kit includes the castings and raw parts required, so you can machine everything yourself—a great project for the aspiring machinist! For those who don't want to machine their own parts, choose the H8102 pre-machined kit instead. The finished project measures 9-1/2"L x 4"W x 6-1/2"H and the base measures 12-1/4"L x 6-3/8"W. Hardware (nuts, screws and washers) not included. Provided plans use metric dimensions and call for making metric threads. Made in an ISO 9001 factory.

The kit arrived promptly and in relatively good order. Some of the parts were loose but everything was there. The heating piston was dented and there is no drawing for that part, so I will need a new piston (Ref.No. 45). I have started machining the parts and I noticed that a measurement is missing on Ref.No.5 (thread length). It will be interesting to continue with the machining and finally the assembly. One question: How is the cooling cylinder fastened to the cylinder base?

I bought a month ago. Packaging is very nice and labeled very clearly. I'm very happy with that. At first glance the prints are nice, but once I started to convert to CAD so I could CNC machine some of the components they weren't as clear. Nothing terminal, but the dimensioning strategy is confusing at best on several parts.
